Overview
The BD5226G-TR is a voltage detector IC from ROHM Semiconductor, designed for monitoring power supply voltages. It features an adjustable delay timer and an open-drain output. The typical under-voltage detection voltage is 2.6V with a precision of ±1%. The reset active voltage range spans from 0.95V to 10V. Operating current is 0.85μA at VDET=4.8V. Hysteresis is set at VDET x 0.05. It operates within a temperature range of -40°C to 105°C in an SSOP5 package.
Feature Summary
- Adjustable delay timer functionality
- Open-drain output configuration
- Wide reset active voltage range
Applications
- Power supply monitoring
- Microprocessor reset circuits
- Battery voltage supervision
Procurement Notes
Verify the specific suffix against official documentation, as the BD5226G series status varies by variant. Confirm RoHS compliance and packaging details directly with the manufacturer or authorized distributors. Ensure the selected part matches the required electrical specifications for your design. Check for any obsolescence notices associated with the base model BD5226G.
Selection Notes
Select this component when an adjustable delay time is required for system reset sequencing. Compare the 0.85μA operating current against lower-power alternatives if battery life is critical. Verify that the 0.95V to 10V reset active range covers the minimum voltage requirements of the monitored circuit. Consider the SSOP5 package size constraints during PCB layout.
Part Context
This device belongs to the BD5226G family of voltage detectors. While the base BD5226G is noted as not recommended for new designs, specific variants like the BD5226G-1 are recommended. The BD5226G-TR represents the tape-and-reel packaging option for this supervisory circuit, facilitating automated assembly processes.
Replacement Considerations
The BD5226G-1TR is listed as a recommended replacement with similar pinout and package. Other potential substitutes include the BU4826F and BD49E26G, though these differ in output type or delay features.
